I bought a canon AE1 (not program) long time ago, and I discover that diaphragm is not closing when i trigger the release button.
My lens (old FD 85mm S.S.C with no release button) is good because it's working on another AE-1. And the battery is good.
I also try to "play" with the diaphragm of the lens when it's unmount. I move the "spindle" (at the opposite side of the red point) and the diaphragm is closing well.
'''What I do : '''
I put the aperture ring to f16, I put the shutter speed to bulb. I arm the camera.[br]
I open the backside of the camera with no film to see what's happening through the lens.
When I shoot and stay the button press, I see that the diaphragm is not close.[br]
-
I suspect the "diaphragm control lever" (cf page 2 of this document [https://www.ifixit.com/Document/hdFUh5VXlBAeBmKH/.pdf |this document] ) because I see the control lever still at the top. [br]

I suspect the "diaphragm control lever" cf page 2 of this service document on [https://www.ifixit.com/Device/Canon_AE-1|this page] because I see the control lever still at the top. [br]
And when the control lever is still at the top, one of the spindle (the spindle that move when I lock/release the lens from the camera) of the lens is also at the top, which prevent the diaphragm to close.
'''I did a second test : '''
I put the aperture ring to f16, I put the shutter speed to bulb. [br]
I arm the camera and I open the backside of the camera with no film to see what's happening through the lens. [br]
But this time, I action the "stopped-down lever", I see from the front of the lens that the diaphragm is now close (finally). I release the "stopped-down lever". Then now I shoot and stay the button press, I see that the diaphragm is close and the "diaphragm control lever" is down ! [br]
Perfect ![br]
If I shoot again but with no "stopped-down lever", the diagram will not close again.
So, why the diaphragm is not closing ?
I have to tell you that the exposure mesure is not functioning, the needle is always go down, even with a lot of light

Hello all,
I bought a canon AE1 (not program) long time ago, and I discover that diaphragm is not closing when i trigger the release button.
My lens is good because it's working on another AE-1. And the battery is good.
I also try to "play" with the diaphragm of the lens when it's unmount. I move the "spindle" (at the opposite side of the red point) and the diaphragm is closing well.
'''What I do : '''
I put the aperture ring to f16, I put the shutter speed to bulb. I arm the camera.[br]
I open the backside of the camera with no film to see what's happening through the lens.
When I shoot and stay the button press, I see that the diaphragm is not close.[br]
I suspect the "diaphragm control lever" (cf page 2 of this document [document|hdFUh5VXlBAeBmKH]) because I see the control lever still at the top. [br]
And when the control lever is still at the top, one of the spindle (the spindle that move when I lock/release the lens from the camera) of the lens is also at the top, which prevent the diaphragm to close.

Thanks a lot
